The theoretical bases are the CAPV curriculum, the competences and the environmental education. In turn, the constructivist vision, the methodology of work projects and evaluation (as regulator of the teaching-learning process) are the means adopted to develop the work.

• The current curriculum, in its section Objectives of Basic Education, establishes in its article 7:

"Basic Education must help students develop their ability to:" N) Become aware of the main problems that humanity presents and that are reflected in the sustainable development objectives.

  • To implement a learning process in interaction and connection with the environment, as a result of a strong mental activity.
  • To start from students' previous knowledge and understanding, in order to build new knowledge and develop new skills; always inside their comfortable self-development zone.
  • To commit with the quality of the teaching content, its meaningfulness and applicability in order fields.

• Evaluation is the axis of work. It is the one that regulates the teaching-learning process. Its function is to analyze the information provided by the process itself, becoming its guide and generating or catalyzing new processes. The evaluation allows the students to control and regulate their own constructive process, that is, the evaluation becomes for the students in a self-regulating element, which allows them to learn to learn. The work consists in imbuing the teaching-learning process with mechanisms of regulation and self-regulation
